   EKKO — HOMEPAGE V2 (EXPERIMENT)
   Isolated from the production homepage. Nothing here is loaded
   by index.html, privacy.html or terms.html.

   Tokens, base, typography, buttons, header, phone frame, footer
   and the reveal system are carried over unchanged from V1 so the
   two versions read as the same brand. Everything below the
   "V2 SECTIONS" banner is new.
